最后，jama也不是一个通用的数组类，相反，它主要关注于与矩阵数值计算相关的数学运算。

Finally, JAMA is not a general-purpose array class. Instead, it focuses on the principle mathematical functionality required to do numerical linear algebra.

So I can concatenate techs plus ivys and assign that result to univs, and then when I print it you'll notice I just get a list of five strings.

和ivys数组用加号串联运算,并把结果赋值给univs数组，接下来我显示下univs的结果,你注意到我得到了一个。
